On Sunday October 11, PNG member-dealer Julian M. Leidman was driving back from a coin show in Stamford, Connecticut in the US when he decided to pull-over and take a stop.
He returned to his minivan to find a window smashed, and two bags of clothing and his laptop stolen - along with two bags containing 1,000 coins worth $159,250.
"Among the scarce coins are 1920-S, 1921, 1925-S, 1927-S and 1932 Saint-Gaudens Double Eagles, and several gorgeous, early half dollars including 1806, 1807, 1826 and some other late dates," said Mr Leidman, according to CoinNews.
"Among the foreign coins is an off-centre 1929-J German 5 Reichsmark silver coin (KM56)."
In response to the theft, the Professional Numismatics Guild (PNG) is offering a $2,500 reward, and has banded together it member dealers to raise a cash reward equal to the value of the coins.
This includes six dealers, who have pledged $10,000 each to help solve the crime.
The money will reportedly be given in return for information leading to the arrest and conviction of the thief or thieves.
Anyone with information is urged to contact the New Jersey Police Department, in whose jurisdiction the theft took place.
In other Saint-Gaudens double eagle news, a 1925-S $20 MS66 NGC is currently leading Heritage Auction Galleries' live online Signature US Coin auction. Lots are due to close between October 22-24.
